A .060 over 351 is a 363 inch engine which seems to fit the rule very well and leaves a couple of inches for measuring error.

I don't know what your budget is but I would buy a Dart Block with Cleveland main saddles and put a 3.5 forged crank in it. The stronger block is going to make more horsepower.

If you can't afford the Dart, use a 76 - 85 truck block and spacers to bring the main saddles down to Cleveland size. Then fill the block, bore it .060 over and go racing.

As of this last weekend, somebody blasted a 9.77

Just those trucks blocks you can do that with? I didnt know that 351c were forged (learning again)and i worry about the main caps on the windsor puttin the spray to it.
Thanks guys i would like to try to do this and not spend a zillion dollars building a motor.I may change cam and heads on my shortblock and start small with the spray just to get a feel.

According to the book "How to Make Short Track Power" by Richard Holdener the truck windsor blocks of that era are what FRPP sells as the 351 Sportsman block. They bore a used block .030 over and sell it as a performance block. They have beefier main supports than other 351 blocks.

The mains in 351W blocks are much stronger than they are in a 302. I don't think you are going to have a problem with them but I would defer to one of the nitrous experts since I have never run spray. I am sure one of them will chime in here before too long.

I am biased towards Edelbrock heads specifically the RPM heads. I think they are good quality and I respect their engineering. I also think any of the top line heads listed would work fine. The cam selection will have a greater effect on performance than the heads will. If you are going racing in a heads up class you will need a cam designed for your combination, not one of the catalog grinds.

If your car is heavy, run the max inches until you have to add weight.
Can you port the heads? Weld and epoxy?
I would run billet steel splayed caps and the best crank and rods you can afford.
There is no limit to the amount of N2O you can spray is it? As long as it is a plate system.....

its 3310 now with no driver but theres weight coming out so that wont be an issue.
No porting of heads
I agree about the the rotating assembly.
There is a restriction on spray like Rustang posted.

Second thought, the chassis set up is probably more important than the engine. You are trying to use the horsepower as efficiently as possible because you can't just add another 100 inches or put on a blower if you aren't fast enough. The 60 foot times will become your standard of excellence.

Good luck and enjoy the experience.

Just a comment about class racing, It is different than anything else you have experienced. Many of the people who class race are very serious and very dedicated to being the fastest. The difference between the winners and losers is often very small so close attention to details is required. When you get advice from someone like Alex who is very experienced in class racing, pay close attention and try his suggestions to the letter.

This is so true! The decision to go this route is out of change after bracket racing for more then 20 years we decided to try this type of racing.I like the heads up style racing and my other car wont fit well into any class (big inches heavy car)so the Fairlane seems to be the perfect platform to launch from.As some know i have been new to the Ford game and with the power i have seen them make i think it is a good match.
If all goes correct 2005 should be interesting.
Thanks guys Dennis
